The invention is fully disclosed in the following specification, ofwhich the accompanying drawing forms a part, said drawing being a planview of the apparatus which I employ, part thereof being in section.

In the drawing forming part of this specification I have shown at a abuilding in which is a room, hall, orcompartment b, at one side or endof which is placed a tubular casing c, which rests upon or is suitablysupported on the floor, and through the casing c is passed a shaft d,provided at one end with a hand- Wheel 61 or other suitable device bywhich it may be turned.

Secured to the casing d are a plurality of tubes composed of separatetelescopic sec-' tions (2, c and e and the outer section 6 is providedwith a perforated head a, and the inner section e is secured to thecasing 0. Each of the telescopic tubes is also provided with a cord orother flexible device f, one end of which is secured to the shaft 06 andthe other to the outer end of the outer telescopic section, and byturning the shaft (1 the cord or other flexible device f is wound onsaid shaft and the tubes are telescoped, as shown in dotted lines.

In the drawing forming part of this specification I have shown four ofthe telescopic tubes, each of which is composed of three separatesections; but it will be understood that these tubes may be of anydesired number according to the size of the hall, room, orcompartmentand may consist of any preferred number of sections or parts.I also provide 19oz. serinnaisasss.

In practice the tubes connected with the casing c are telescoped, asshown in dotted lines, and the valve g is then opened, and the air isallowed to pass into the casing c. The air from the casing 0 passes intothe telescopic tubes and out through the perforated heads 6 thereof, anddust, dirt, and other substances on the floor of the hall, room, orother compartment are blown to the side of the room opposite the casingc and may be taken up and my invention is not limited to the details Iof construction herein described, as many changes therein andmodifications thereof may be made without departing from the spirit ofmy invention or sacrificing its advantages.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. An apparatus for cleaning the floor of a compartment comprising acasing at one side thereof, collapsible tubes composed of separatesections and connected with said casing and ranging transversely of thefloor of the compartment, and the outer section being provided at itsouter end with a perforated head, devices for collapsing said tubes, and
